The Guardian is a beautiful boot, made of full-grain tumbled nubuck. A benefit of the Guardian is its focus on flexibility. The composite LENZI® plate allows your feet  to move freely, while still protecting your soles from sharp objects. The Ignite hi also features a flexible PU midsole, to work with your feet so you can focus on working hard. The Guardian will keep you safe, with high-abrasive and slip resistant soles and steel toes.
